Here is one for you with M + 18-55 IS STM - Transfagarasan, Romania:
It's great in terms of sharpness, I have made some contrast adjustments, but the clouds and everything else are real.
Extreme metal festival with M + 22mm? No problem - Alan Averill(Primordial):
That was a really nice moment with the clouds hanging in there. I have done many shots at Swiss mountain passes, but didn't have any luck with a low hanging cloud cover like that. Instead I have often seen clouds hanging way below these high mountain passes. How high is that pass in Romania?
